Does FNV: Ultimate Edition for PC has two disc or only one? I know that russian and german versions have 2 discs, but I`ve seen unboxing videos of US version of FNV: Ultimate Edition and it had only one disc. Does this disc include all dlc or they will be downloaded separately trough Steam?

I want to order Ultimate Edition from american Amazon as a gift for my friend. Digital version trough Steam unfortunately isn't an option (but i do know that retail version still needs to be activated on Steam).

P.S. Sorry for my English
